Transformation Of Graph Dse Exercise -

Complete Guide: Transformation of Graphs (DSE Mathematics)

x‑axis

(a) Vertical stretch by factor 3. (b) Horizontal compression by factor ( \frac12 ) (i.e., ( a=2 )). (c) Reflection in the , then shift up by 1 unit.

• Nodes: A, B, C, D, E
• Edges: AB, BC, CD, DE, AC

6. Common Mistakes to Avoid

f(x) = -((x - 2)^2 + 3) → f(x) = -2((x - 2)^2 + 3) transformation of graph dse exercise

• Vertical stretch by factor 2
• Reflection in x-axis (due to negative)
• Vertical shift up 4 units

Overview

Every year, students lose valuable marks because they confuse a "translation" with a "reflection" or forget the golden rules of scaling. Nodes: A, B, C, D, E Edges: AB, BC, CD, DE, AC

• $y = f(x - h)$: Move right (opposite sign).
• $y = f(x) + k$: Move up (same sign).
